My next mod is going to be the dual pass endplate and so my question is what kind of temp drops did everyone see before and after the dual pass?

 

WHY? You have plenty of cooling now!

 

Its still staying around 140-150

 

Then something IS not right. You have the same setup and tune (basically) as me...

I was 100-110* IAT2

Are you sure you are spraying.... did you put the hose out the hood and watch it spray out when you get into boost?

 

check that pump... and cooling will always help... might not get u hp but it will keep the hp u start out with b4 it heat soaks longer.... i heard its a 2 day job to do it... i am thinkin about doing it when i get my blower ported.

 

The meth seems like it gives it more power but it really doesnt cool it down. You had a 2.8 though and i have the 2.7 right

 

Uh, NO I had a 2.7 too as well as a 2.6 at the end...

My highest IAT2 was 117* at the track after 5 runs!

 

Yea its spraying i definitely know that

 

Then your mixture isn't right....

Get 1 gallon of distilled water and 5 bottles of HEET.

Mix the 5 bottles of HEET in a CLEAN empty 1 gallon jug, the rest with the distilled water!

 

Ok but it usually gets up to 150 and i hardly get into the boost for it to spray so just normal driving it gets that high

 

normal driving.... you may want to check your H/E pump then.... because out of boost the meth wouldn't spray anyway!

Empty your H/E and fill it with 70% distilled water and 30% Dexcool coolant and some Water Wetter

 

Yea the heat exchanger has that mixture in it. The pump has to be working from what i can see cause it will drop a lil when i get on it a lil which kicks the pump on.

 

No your H/E pump not the meth pump! Because that is higher than the last time you were out here!

 

Yea i am talking about the H/E pump and my temps have always been around 140-150 since putting on the 2.7.

 

Something isn't right dude.... your meth doesn't spray untill 6psi so under no or very low boost situations you are only on the H/E...

You shouldn't be that high without something being up...

 

Thats what i was thinking but i am pretty sure the h/e pump is working because it bleed itself out when i recently switched it to distilled/dexcool

 

I dont' know... maybe you have some air in the lines... but it shouldn't be that hot just under non-WOT conditions
